Abstract: Objective To explorethe effect of pelvic floor peritoneal reconstruction on the effect and complications of minimally invasive low anterior resection in patients with rectal cancer. Methods 128 patients with rectal cancer who received minimally invasive low anterior resection in our hospital from January 2017 to January 2021 were selected as the research subjects, and the subjects were divided into two groups according to the surgical method, and 64 cases underwent pelvic floor peritoneal reconstruction surgery 64 patients without pelvic floor peritoneal reconstruction were included in the control group and were followed up for 6 months. The surgical results and perioperative indicators of the two groups were compared and analyzed. Results The operation time of the observation group was significantly higher than that of the control group （P<; 0.05）. The postoperative hospital stay in the observation group was significantly lower than that in the control group （P<; 0.05）. The incidence of anastomotic leakage, grade C anastomotic leakage, abdominal infection, pelvic infection and intestinal obstruction in the observation group was lower than that in the control group, and the total incidence of complications in the observation group was significantly lower than that in the control group （P<; 0.05）. The second operation rate in the observation group was significantly lower than that in the control group （P<; 0.05）. There was no significant difference in serum C-reactive protein and procalcitonin levels between the two groups at 1, 3, and 5 days after operation （P>; 0.05）. The original level was lower than 1 day after operation （P<; 0.025）. The stool function scores of the observation group after operation, 1 month after operation and 6 months after operation were significantly lower than those in the control group after operation, 1 month after operation and 6 months after operation （P<; 0.05）. Conclusion Pelvic floor peritoneal reconstruction can greatly reduce the risk of grade Ⅲ~Ⅳ complications in patients with rectal cancer who undergo minimally invasive low resection, and also reduce the incidence of secondary surgery. Prognosis is facilitative.
